Step-by-step explanation:
4 + 1/2+1+3/5
5+1+1/10=6 1/10
Third option is the correct answer.
Answer:
Step-by-step explanation:
![y - y_1 = m(x - x_1) \\ \\ y - 0 = \bigg[ \frac{2b}{(2a - c)} \bigg] (x - c) \\ \\ y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2b}{(2a - c)} \bigg]c \\ \\ \purple { \boxed{ \bold{y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2bc}{(2a - c)} \bigg]}}} \\](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29%20%5C%5C%20%20%5C%5C%20y%20-%200%20%3D%20%20%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5D%20%20%28x%20-%20c%29%20%5C%5C%20%20%5C%5C%20y%20%3D%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dx%20-%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dc%20%5C%5C%20%20%5C%5C%20%20%5Cpurple%20%7B%20%5Cboxed%7B%20%5Cbold%7By%20%3D%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dx%20-%20%5Cbigg%5B%20%5Cfrac%7B2bc%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5D%7D%7D%7D%20%5C%5C%20)
So.. notice the picture below
and thus, we also know, that A = 51, thus

now, the height is just a value, it can't be negative, thus we can rule out -17, thus h = 6
and surely you'd know what the base is
The answer is 20. Hope this helps!!!
